Vacuum current and polarization induced by magnetic flux in a higher-dimensional cosmic string in the presence of a flat boundary
E. A. F. Bragança, E. R. Bezerra de Mello
In this paper we analyze the vacuum bosonic current and polarization induced by a magnetic flux running along a higher dimensional cosmic string in the presence of a flat boundary…
Scalar self-interaction in the spacetime of a cosmic dispiration
K. E. L. de Farias, E. A. F. Bragança, H. F. Santana Mota
In the present paper we investigate the classical self-interaction associated with a charged scalar point particle placed at rest in the gravitational field of a linear topological…
Vacuum bosonic currents induced by a compactified cosmic string in dS background
E. A. F. Bragança, E. R. Bezerra de Mello, A. Mohammadi
In this paper, we investigate the vacuum bosonic currents in the geometry of a compactified cosmic string in the background of the de Sitter spacetime. The currents are induced by…
Induced Fermionic vacuum polarization in dS spacetime with a compactified cosmic string
E. A. F. Bragança, E. R. Bezerra de Mello, A. Mohammadi
We study the fermionic condensate (FC) and the vacuum expectation value (VEV) of the energy-momentum tensor for a massive spinor field in the de Sitter (dS) spacetime including an…
Vacuum expectation value of the energy-momentum tensor in a higher dimensional compactified cosmic string spacetime
E. A. F. Bragança, H. F. Santana Mota, E. R. Bezerra de Mello
